That's not the case, and it's a bit frustrating to read this just after
I wrote a mail explaining this point. To reiterate:

* With separate ways, we don't know which road section a sidewalk
belongs to.
* This knowledge is necessary for many applications.

For such a fundamental property, "research scientists believe they can
use the spatial proximity" is not good enough imo. It has to be
practical to obtain this relationship from OSM data.
